val kappa : float
The factor by which the radius of a circle is multiplied to find the length of the bezier control lines when approximating quarter arcs to make circles.
val restrict_angle : float -> float -> float
Calling restrict_angle s a
restricts an angle a
to one of those at s,
2s, 3s...
returning the chosen one.
val circle : float -> float -> float -> path
Calling circle x y r
builds a path representing a circle at (x, y)
with
radius r
.
val rectangle : float -> float -> float -> float -> path
Calling rectangle x y w h
builds a path representing a rectangle with top
left (x, y)
, width w
and height h
.
